Biggest tire on Stock 67-69 Dart

Yes. Mine will have a stock 8 3/4. Who sells stock steel rims(SBP) with the 4.25 BS? I have been looking at rims and can't find them. They all seem to have 3.75 BS (will that work??). I'm thinking of keeping my 205/60 -14 in front and getting a set of 15x6 with 235/60-15 M&H racemaster drags. Mine car still has the SPB axles on them. I would like to keep the axles if I can find rims for it.
Thanks
